Abstract:
Described herein is a system and method for preemptive chassis control intervention for an autonomous vehicle having a mechanical system and a chassis controller. The chassis controller is configured to output a consumption signal that represents a percentage of an activation threshold consumed by an operation monitored by the chassis controller, wherein the chassis controller is activated to manipulate the mechanical system when the activation threshold is reached. A computing system of the autonomous vehicle receives the consumption signal output by the chassis controller to determine a path plan for the autonomous vehicle based upon the percentage of the activation threshold consumed by the operation monitored by the chassis controller. The computing system further controls the mechanical system to execute the path plan to preempt activation of the chassis controller.
